Description
Technical field
The present invention relates to the layout of turbine blade inner cooling channel.
Background technology
Turbine blade, particularly gas turbine blades are high capacity assemblies. In operation,Under high rotating speed, rotate. Therefore, high mechanical properties is necessary. In addition particularly exist,In the situation of gas turbine blades, in operating process, produce high temperature. Common situation is,Drive the higher temperature of the admixture of gas of turbine blade to have the efficiency of combustion gas turbinePositive role. In this case, in order to prevent too high turbine blade temperature, turbineBlade is cooled. For this purpose, cooling duct is often arranged in turbine blade inside.
Once in a while, turbine blade is damaged by clashing into foreign matter. The consequence of this damage may be comeThe problem of the air of self-cooling channel, and sometimes significantly damage the cooling of turbine blade. ThisOften cause the blade damaging to be had to by quick-replaceable.
US6382914B1 discloses a kind of for distribute cooling fluid in turbine bladeArrange. One row cooling duct is provided in this inner space that is arranged in turbine blade, and it is flatThe capable leading edge in turbine blade is also parallel to trailing edge extension. At least some cooling ducts are by diagonal anglePassage is connected. Design is cooling in order to improve like this.
Be used for other cooling structures of turbine blade from document JPS59231103A,Known in FR1209752A, GB827289A and US3014693A.
According to the layout of above-mentioned document, particularly US6382914B1, damage at turbine bladeIn bad situation, can be in some way, contribute to remain to a certain extent cooling,Thereby impliedly contribute to cooling duct. This does not specify in the literature, and in fact onlyApproved according to the present invention described below.
Summary of the invention
The object of the invention is further to improve in the situation that there is cooling duct damage cooling.
This purpose realizes by independent claims. Favourable configuration can be in subordinateIn right, find.
Multiple cooling ducts in a kind of turbine blade are proposed, i.e. at least two cooling ductsArrange, for delivery of cooling fluid. Cooling fluid is air normally.
Cooling duct is directed to one or more cooling fluid outlets by turbine blade.
For this purpose, turbine blade generally has root of blade, vane airfoil profile tip, leading edgeAnd trailing edge.
In this case, cooling duct is connected to each other and divides each other in other regions at specified pointFrom extension, the in the situation that of making to occur turbine blade damage in region, a cooling duct,Cooling maintenance to a great extent by other cooling ducts is without prejudice.
In the prior art, common situation is that cooling duct extends to along leading edge from root of bladeVane airfoil profile tip. Owing to damaging the leakage causing and cause cold in this position in this cooling ductBut fluid flows out. This is problematic, because it can interrupt being positioned at those regions of leaking downstreamInterior is cooling.
But, if be designed to further pass through turbine from the cooling fluid of this cooling ductIt is cooling that machine blade meanders through and provides, and it is debatable especially. In the situation that occurs to leakUnder, the cooling of turbine blade lost efficacy substantially.
This problem can adopt concept presented above to be reduced, according to above-mentioned concept, coolingPassage is connected to each other and separated from one another in other regions at specified point. Rely on the company at specified pointConnect, cooling fluid can be delivered to another cooling duct from a cooling duct. If leakedWill in other cooling ducts that connect upstream, occur, downstream in the situation that not connectingCooling will inefficacy. This connection makes to connect the cooling of downstream and can be tieed up to a great extentHold. But, in other regions, be also necessary cooling duct separated from one another. Do not separatingSituation under, if leaked, cooling fluid can flow to leak in the clear,Make cooling will be again impaired more significantly. But, first, at normal operation period, alsoIn other words in the time not there is not leakage, have channel design, that is, the separation of cooling duct is also mustWant in fact guide cooling fluid to pass through whole turbine blade. Otherwise, cooling fluidShort path along outlet from cooling fluid inlet to cooling fluid is flowed. Therefore, having all the time mustProduce the acceptable balance between connection and the separated region between cooling duct. ConsiderAbove-mentioned explanation, those skilled in the art can realize a large amount of different layouts.
In this case, an important aspect is that at least one cooling duct starts from leaning onNearby edge and the region near root of blade, and as corner channel is extended through to turbine bladeEnter the region near trailing edge close vane airfoil profile tip. Be that as it may, importantly clarificationNeedn't originate in root of blade or leading edge to corner channel, and be only in this region.
But, start should not be left out at root of blade and leading edge place. This is equally applicable toTo the end of corner channel near trailing edge and near vane airfoil profile tip. Corner channel is made likelyEasily guide cooling fluid to enter each region of turbine blade, and guarantee everywhere effectively coldBut.
In the situation that occurring to leak, layout even as above can not be avoided cooling being subject toDamage, or even in area failures out of the ordinary. But generally speaking, the loss of cooling fluid greatlyReduce, and at complete leaf area, be coolingly guaranteed to a great extent. Therefore, machineIt is injury-free that tool stability and intensity keep to a great extent. This allows the turbine leaf damagingSheet continues operation.
Even if still keep for a long time changing turbine blade, if this can wait for until whirlpoolThe overhaul next time arranging of turbine, this will be very large advantage. Conventionally, the temperature of rising is notCan cause immediately no longer acceptable damage turbine blade, and only in the operation of overheated lower angular lengthAfterwards.
Although illustrate and relate generally to the cooling selected of rotor blade, this rotor blade is by bladeRoot is attached to rotor, and the cooling concept of imagination can also be used for guide vanes in principle.
In one embodiment of the invention, specify that cooling duct is connected to each other, made to work asWhen this layout is flow through, cooling fluid regularly flows into another cooling leading to from a cooling ductRoad. But, also it is contemplated that this layout be only provided in the situation that there is leakage. In order to haveImitate through-flow object, proved that it is favourable also providing this layout during normal operating.
In one embodiment of the invention, cooling duct is by porous plate or be porous plate modeDevice separate from the inwall of turbine blade, make cooling fluid can be substantially perpendicular to whirlpoolThe inwall of turbine blade arrives this inwall. It is cooling that this has realized so-called impact. This is effectively,Once because cooling fluid becomes turbulent flow at inwall place and heating flows away again. If cool streamBody just flows through the inwall of turbine blade simply, and tight adjacent wall forms relatively weak flowingFilm will be possible. In addition, only in a region, heated cooling fluid will be usedIn cooling other regions.
In one embodiment of the invention, at least one cooling duct starts from root of blade,In the region of the leading edge near turbine blade. As also known layout from prior artSituation, due to reasons in structure, the entrance of cooling fluid is normally at root of blade. Due to drivingThe admixture of gas of turbine blade is the warmmest at leading edge place, is exactly here on turbine bladeThermic load is the highest. Therefore to start from leading edge region be expedient in cooling duct.
In further embodiment of the present invention, two cooling ducts start from root of blade,Near in the region of leading edge, and end at the region near root of blade, they there byBe connected to each other and be connected to corner channel. This allows the cooling fluid of cooling fluid from root of bladeEntrance is delivered to corner channel. If cooling fluid is because leak from above-mentioned one of them cooling leading toIn road, flow out, still can be supplied to cooling fluid by other cooling duct to corner channel.
In further embodiment of the present invention, other cooling ducts are from diagonal angle channel branch,Wherein especially, cooling duct in the direction top set of trailing edge and/or cooling duct at vane airfoil profileMost advanced and sophisticated direction top set. Therefore, can be further excellent in the whole region of turbine bladeChange the distribution of cooling fluid.
In further embodiment of the present invention, upwardly extending in the side at vane airfoil profile tipThe cooling duct that above-mentioned cooling duct leads to, is parallel to the most advanced and sophisticated extension of vane airfoil profile. Be parallel toThe most advanced and sophisticated cooling duct of extending of vane airfoil profile can lead to identical to corner channel in this caseRegion.
In further embodiment of the present invention, at the cooling duct base of trailing edge direction top setIn basis, extend perpendicular to trailing edge. Alternately or additionally, on vane airfoil profile tip direction, prolongThe cooling duct of stretching is arranged essentially parallel to trailing edge and extends. This is also for further optimizing cooling fluidDistribution. The object of doing so is always, answers the least possible weakening in the leakage of a positionTurbine blade cooling.
In further embodiment of the present invention, cooling fluid outlet is present in the region of trailing edgeIn, cooling fluid can be delivered to turbine leaf from the region in turbine blade by this outletThe region of sheet outside. Therefore, in trailing edge region, likely realize the further cooling of outer wall.The cooling fluid having left can be alternatively for driving other stage of turbine.
In further embodiment of the present invention, at least one cooling fluid outlet is present in bladeRoot, in the region of trailing edge. Cooling fluid can be from cooling fluid inlet, and it normally existsRoot of blade is in the region of leading edge, flows through turbine blade and is back to trailing edge regionInterior root of blade. The cooling fluid leaving can be reused for cooling other turbinesBlade.
